Adafruit has presented the Metro RP2040, a new development board based on the design of the Arduino UNO. Specifically, Adafruit has created the Metro RP2040 as a drop-in replacement for the Arduino UNO thanks to its compatible form factor. As its name implies, the Metro RP2040 also relies on the Raspberry Pi RP2040 microcontroller, which offers a pair of ARM Cortex-M0+ cores clocked at 133 MHz.
Moreover, the Metro RP2040 ships with 264 kB of embedded SRAM courtesy of its microcontroller, as well as 24 GPIO pins and a Programmable Input/Output (PIO) block. According to Adafruit, the Metro RP2040 supports Arduino IDE, plus C, C++, CircuitPython and MicroPython. Meanwhile, all programming is handled via a USB Type-C port. It is worth noting that although the USB Type-C port can provide power, Adafruit has included a DC jack with an on/off switch that delivers 6-12V.
Furthermore, Adafruit has integrated a microSD card reader, an RGB NeoPixel LED and a secondary LED. Currently, Adafruit sells the Metro RP2040 on its website for US$14.95 before shipping and taxes. Please see Adafruit’s website for further details.
Prior to writing and translating for Notebookcheck, I worked for various companies including Apple and Neowin. I have a BA in International History and Politics from the University of Leeds, which I have since converted to a Law Degree. Happy to chat on Twitter or Notebookchat.
